Sobel
This Matlab code shows how to perform edge detection by Sobel method in horizontal & vertical direction and the effect of increasing and decreasing the threshold value . Besides, you can try to perform the edge detection by other method in the same ways such as Prewitt , Roberts , Canny and others.

说明: 普通显示技术是根据几何光学成像原理,记录下光波的振幅,将空间物体成像在一个平面上。由于丢失了光波的相位信息,因而物体的信息是不完整的。全息图因能够完整地记录物光波的振幅和相位,因而能够包含物体的全部信息。菲涅耳全息术作为全息术的一个分支,更是得到了飞速的发展,已经广泛应用于全息干涉计量术、全息存储、全息光学组件、全息显微术等各个领域。
本论文主要研究菲涅耳全息图的编码与显示过程。经典光全息术包括波前记录和波前再现两步。全息波前记录将物光和参考光以干涉条纹记录成全息图,此全息图同时记录了物光波的振幅和相位 然后用参考光照射全息图,该参考光经过衍射后,即可再现出原始物体。
计算全息是将先进的计算机技术和光全息术结合起来,利用计算机产生全息图。它不需要物体实际存在,而是把物波的数学描述输入计算机处理后,绘制出全息图,然后用光学方法重现。本文采用计算全息方法,利用Matlab模拟光线的菲涅耳衍射传播,用计算机生成菲涅耳全息图 ,并由所生成的全息图再现出原始图像 ,完成全息图的数字再现。
